Panoramic vision system has wide prospects in maritime surveillance applications. But it is always lack of target detection technology support. According to the complexity of sea-sky background and the specificity of panoramic images, a novel long-range small target detection algorithm based on sea-sky line extraction is proposed in this paper. Firstly, the reasons that gradient Hough circle transform...
Omnidirectional vision system has wide application prospects in maritime surveillance applications for its advantages of unified imaging, 360-degree view and rotation invariant. But it has weak support in techniques of target detection. With the complexity of sea-sky background and the specificity of omnidirectional image, this paper is carrying out the small targets detection on the sea based on...
